I have used Valerian Root off and on over the years, it sometimes helps. I drink Earl Grey tea at night and find some benefit, though it may be in my head, as it has some caffeine in it. Things I have read on but not tried is passion flower, kava, and st. johns wart. My go to crutch over the years has been benedryl or diphenhydramine, but it is not natural and has digestive side effects if used too often.
